PACKING.

30 Drawing.

To all whom it may concern:

Be it known that I, ADAM DAUM, a citizen of the Dominion of Canada, residing in the city of Portage la Prairie, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Packings, of which the following is a specification.

My invention deals with im rovements m packings and more particular y to paclnngs used for steam, hot and cold water attachments, and is especially recommended for valve stems as it never hardens and slicetively prevents leakage, at the same time leaving the stems nice and'free to rotate. It is particularly adapted for use in all manner and shapes as it is madev up invbulk and to use, lumps of it are simpl broken off and kneaded into the size to t the box, goint, or lace where the packing is require y improvement packing comprises the following substances or ingredients mixed in the ollowing proportions; Lead wool nine parts, asbestos fiber three parts, graphite four-fifths parts, cylinder oil one and three-fifths parts, tallow one and threefifths parts.

The quality of the improved packing depends on the proper proportions and a thorough mixing and in preparing the pack- Spceiflcation of Letters Patent.

Application med Kay 20, 1914. Serial No. 889,841.

in I first proceed to mix the lead-wool and as estos fiber and it is essential that these be properly worked and mixed in order to insure that it will be thoroughly intermingled with theother ingredients. Next the tallow, 011 and (graphite are heated together and stirred an then the mixture of leadwool and asbestos fiber is added and the whole is thoroughly stirred. Afterward the mixture is put under hydraulic pressure and the improved packing is then produced in lumps and to, use, it is only necessary to break ofi the size required and knead with the hands and apply as stated above.

Having thus described the invention what I claim and desire to secure by Letters Patent'is:

An improved packing comprising lead woolnine parts; asbestos fiber-three parts; graphite'four-fifths parts; cylinder oil-one and three-fifths parts; tallow-one and three-fifths parts, substantially as herein set forth and described.
